*How it Works
*

   1. TomcatA starts up
   2. TomcatB starts up (Wait that TomcatA start is complete)
   3. TomcatA receives a request, a session S1 is created.
   4. TomcatA crashes
   5. TomcatB receives a request for session S1
   6. TomcatA starts up
   7. TomcatA receives a request, invalidate is called on the session (S1)
   8. TomcatB receives a request, for a new session (S2)
   9. TomcatA The session S2 expires due to inactivity.

section describes the steps.7-9 steps confusing.
Does tomcat 6 even support such scenario?

Re: Apache Server failover and session replication

Shaun,
 Yes we have a user session object created when user logs on with proper
credentails.
For ex: At startup of two servers lets say user A has logged in.
As you are saying the SSO information is propagated while all instances are
running. So when for first time when tomcat which was handling request goes
down, this session object is successfully handled by other tomcat instance.
But when first instance comes up, and due to some reason second instance
which was processing sticky requests goes down this session object is lost.
Our problem is that this failback should happen correctly, and we find this
a general requirement, so do tomcat6 support such a scenario?

I have been sratching my head from past few days to fix this. What kind of
solution have you written for this? Could you please share?

Thanks for your time,
Ciao,
Sumedh

Re: tomcat 4.1.31 problem

2009-09-02 Thread jamez smith

Hi Mark,

Tomcat is only used for local development environment.  In our production,
we use Websphere application server on AIX.  I am also new to this project
and was told I can only use Tomcat 4.1 to setup my local development.

I like to clarify that the JVM 1.4 is no longer supported by Sun?

Thanks,
Jamez.

You should use the setAttribute method for anything that doesn't have it's

Re: Apache Server failover and session replication

2009-09-02 Thread Shaun Senecal

We had a similar problem with Tomcat 6 using clustering.  It turns out that
the SSO information is only propagated while all instances are running.  If
Instance-A fails, several users then log in to Instance-B, then Instance-A
comes back up, all of the SSO information for the users that logged in
during the downtime is not included in Instance-A so those users are forced
to re-login once the load balancer sends them to that instance.

I wrote a fix for it, which might be useful for you.  However, it hasnt been
fully tested and is designed to only share the SSO information at startup,
not all Session information.  If Tomcat doenst handle this case, then the
fix I wrote should be easily extended to handle that.  Basically, when an
instance comes up it broadcasts a request for all known SSO information to
the cluster.  It then takes the first response it gets and continues
processing as normal.

Let me know if you dont find a proper solution to the problem and I will try
to dig up that fix.  My intention was to post it back to the group, but I
got sidetracked once we (temporarily) stopped using clustering.

Re: thread dumps catalina.out

2009-09-02 Thread Jim Cox

Nothing magical to the two terms, just makes it easier to have a
tail/tee combo running while issuing the kill -QUIT cmd (v. via job
control, e.g).

For example, in terminal A:
prompt#tail -f /usr/local/tomcat/logs/catalina.out | tee /tmp/tomcat.dump.A

Now in terminal B:
prompt#ps -aef | egrep '[t]omcat'
root 17660 1  0   Sep 01 ?6:15 /usr/java/bin/java
-Dtomcat=1 -Xmx512m -Djava.awt.headl

root  8917  8899  0 23:41:01 pts/30:00 tail -f
/usr/local/tomcat/logs/catalina.out
prompt#kill -QUIT 17660
prompt#

After stopping the tail/tee combo in Term A (with Ctrl+C):
prompt#ls -alF /tmp/tomcat.dump.A

reconfiguring tomcat logging

2009-09-02 Thread Chris Cheshire

Whenever tomat compiles a JSP page and there is an error in it (for
instance trying to reference a property on a bean that doesn't exist),
it is throwing (and obscuring) an exception and logging it to
catalina.out and then returning whatever html it has built to the
browser, as in :

Sep 2, 2009 2:07:28 PM org.apache.catalina.core.ApplicationDispatcher
invokeSEVERE: Servlet.service() for servlet jsp threw exception
javax.el.PropertyNotFoundException: Property 'blah' not found on com.foo.bar

(and then a ginormous stack trace)

This would be good if I knew which host actually had this error. I
have one tomcat instance server with a number of hosts, each a sandbox
for a developer.

Is there any way to configure the logging per host such that these
errors that get logged to catalina.out get logged to a host specific
log file instead of catalina.out (or as well as)? I am looking at the
document at http://tomcat.apache.org/tomcat-6.0-doc/logging.html, but
I just don't see/understand what I need to do.

This is not to be confused with logging generated from within my
context - I have that configured via logback going to its own log file
successfully - it's the tomcat engine errors that I need to deal with.

Or, if this isn't possible, is there a way to configure tomcat to
generate that stack trace about the PropertyNotFoundException as the
output html when it tries to compile the JSP instead of obscuring it
and returning a partially complete html page?

Thanks

mod jk - multiple applications, different server clusers, sticky sessions

2009-09-02 Thread Jason Wright

Hello,

I've an interesting situation with our application clusters. I am running
multiple applications for one of our websites. We don't share sessions
between the different servers; we use sticky sessions instead. Session
replication is difficult because of the large size of our users' sessions.

We use applications A & B. I would like application A to run on servers 1
and 2 and application B to run on servers 3 and 4.

The user initially requests application A and receives a sticky session for
server 1. Later, the user requests application B. Since the sticky session
was set, server 1 is accessed, but application B is not found. If
sticky_session_force is set, then another server is tried; however, the
sticky session will still be set to server 1 and the application B may not
use the same server.

I've thought of 3 possible ways to solve this problem with a preference to
the one I don't know how to do yet.

The first (my preference) is to be able to use multiple sticky sessions, one
for each application. This might involve multiple copies of modjk loaded by
tomcat with multiple workers.properties files, or something like that. I
would have no idea of how to do this. Does anyone know how to do this?

The second way of solving this problem is to use multiple copies of Tomcat
bound to different IP addresses with different configuration files. This
solution would be seen as subdomains to the user.

The third way of solving this problem is to use multiple copies of Tomcat
bound to different ports (same IP address) with different configuration
files. This solution would have the same domain, but different port numbers.


I'm pretty sure that the second and third solutions would work, but I'm not
sure about the first solution. I've searched extensively and haven't found
anyone with the same problem. Has anyone on this list been in this situation
or know the best way to solve this problem?



Thanks in advance,
Jason Wright

It is irrelevant. Tomcat doesn't give two hoots about the data it is
processing. It is the application(s) you choose to run on Tomcat that
would need to be compliant.

Apache Tomcat ICD-10 compliance

Please indicate if there is a document that references Apache Tomcat icd-10 
support as my searches of the Tomcat FAQ and Tomcat related websites have not 
produced any hits. My US based employer is a health care based organization 
that requires that we research every application to determine if there is a 
roadmap to support the migration to icd-10 by 2013.   My initial response to my 
employer that there is a low likelihood of any issue with Tomcat and icd-10 was 
rejected as not being sufficiently 'official'.  Thank you.

On the other hand only having it in a separate binary will still prevent

At least we are not aware of any problem with the chunked encoding code.

Thanks for the generally positive answer :).
We're going to try to enable it out of the box on our IIS configurations 
and see how things go, so pretty soon, there'll be alot more machines 
potentially running with the chunked encoding option.


I haven't looked that closely at the code, but was there enough worry 
that it would cause side effects to make it a compile time AND a

Rainer,

Thanks for the reply. I was confused in my orginal post: I am not  
using JBoss at all, only mod_jk.


The file contents are as follows below.

Apache has a hosts directory, but I'm not sure if the files matter.  
They are either the apache .default files or slight modifications of  
them,

e.g. virtual_host_global.conf contains just:

I am using a mod_jk connector with JBoss.

Any help on how to diagnose what the seeming error is pointing to

be much appreciated.


This log snippet is not useful, because the request you used was for
/server-status, which is most likely not a request you want mod_jk to
send to JBoss.

Please post all your JK directives from your httpd.conf and the files
included in that. Also post your workers.properties, and if you use it
the uriworkermap.properties file.

The most common cause why simple setups do not work is the use of
virtual hosts in the Apache configuration. If you have virtual hosts,
you have to put JkMount into the virtual hosts, or you set  
"JkMountCopy

All" in the global part of the configuration.

Rainer

You can check it out from subversion:

svn checkout
http://svn.apache.org/repos/asf/tomcat/sandbox/tomcat-oacc/trunk/

It comes with ant build file and documentation and is easy to build and
install. We didn't release it yet, so you can't download a binary for it.

The configuration is identical to TC 5.5 cluster and 99% of the code
also (and in sync with the latest cluster code in TC 5.5).

Let us know your experiences with it!

Depending on the JVM the dumps usually start with a header like "Full
thread dump..."

Recent Java 6 JVMs also add a timestamp to this header.

Re: 100% usage and hanging on startup of Spring/Hibernate app in Tomcat 5.5 on Ubuntu 7

2009-09-02 Thread Bradley Wagner

Thanks for the clarification on the initial heap size. I've set both Xms and
Xmx to 512m for the following test.
I was able to reproduce the problem immediately with:
- Xms and Xmx both set to 512m
- Java 1.6 with no JPDA running
- XX:+PrintGCDetails enabled

I've attached the thread dump which I took on the 3rd or 4th attempt after
the process hung. They were all the same on each measure.

I've also attached the catalina.out log which shows the GC basically
freezing.

One thing that it is a little odd is that the Catalina log is basically in
the middle of (or possibly JUST finished) some kind of hibernate
initialization but the blocked thread (the only thread doing anything but
sleeping) doesn't really indicate this.

I prefer to use jstack, since I can control where the output goes for each dump.

Re: thread dumps catalina.out

2009-09-02 Thread Jim Cox

FWIW, I usually do a tail/tee on catalina.out in a term, then do the
kill -QUIT  from another term, then kill the tail/tee
combo which leaves me with a reasonably clean thread dump.

For example:

Terminal A:
prompt$ tail -f /usr/local/tomcat/logs/catalina.out | tee
/tmp/tomcat-threads.tmpA

Terminal B:
prompt$ kill -QUIT 12345

thread dumps catalina.out

2009-09-02 Thread keeplearning


Hi All,

I have a quick question about getting thread dumps. I have been told that if
I do kill -3 , it will send the thread dumps to catalina.out.

Let say if I run test 1 and take 3 dumps. Then if I run test 2 and 3 more.
Do these get appended to first thread dumps I took?

If yes, Let say if I run 3 different tests and take 3 dumps each test, how
should I seperate those dumps as per specific tests. How do you guys
normally do it?

Difficult to answer. My feeling is, that the code is fine and the
original contributor Tim Whittington seemed to have used basically the
same code for quite some time.

On the other hand only having it in a separate binary will still prevent
most people to use it, so it might still not be used broadly out in the
field.

At least we are not aware of any problem with the chunked encoding code.

I am using Tomcat session clustering and Apache Http Server for LB(using

Don't know, whether this is still relevant after a couple of weeks: yes,
the above is true, at least since a couple of versions of mod_jk.

Previously it tried to detect the MPM during build, but that was broken
for some platforms like AIX, so we thought it's safer to assume a
threaded environment by default, also allowing to switch between the
MPMs without recompilation of mod_jk.

Hmmm, do your have the SSL session timeout in Apache set to 600 seconds?
It would indicate, that there's a problem with session renegotiation and
client certificates. Usually this should work.

Check the SSL session timeout to see, whether your 10 minutes could come
from the (and choose another value to verify, that the 10 minutes change
accordingly).

If this is true, I would first update to a recent version of Apache and
OpenSSL in order to rule out bugs there.

Another possibility could be a browser bug. Does it happen for varous
browsers, like MSIE and Firefox?

Some general information about this situation is contained in the mod_jk
docs page:

http://tomcat.apache.org/connectors-doc/generic_howto/proxy.html

It is mostly about AJP13, HTTP and reverse proxies and not mod_jk specific.

I don't have a nice answer, but I would

- use a script for the common tasks, like changing the activation state
- use administrative discipline for the unspecific rest of changes

jkstatus uses only GET requests, and the URLs are easy to compose. So
you can have a script using e.g. curl as an http commandline client and
looping over the nodes of your farm to apply chnges for all nodes. The
script can be run on any node, that has web access to jkstatus of all
Apaches. curl also knows how to do basic auth.

I plan to add saving of config changes, but this will not obviously
solve the replication problem. The saved changes will be most likely in
the form of a change protocol which gets replayed (added to the
workers.properties) during startup. So in a distributed situation you
would still need to apply the changes to all nodes.

Farm management is currently not close (in time).

Rainer

Unfortunately the answer is: mod_jk uses the AJP13 protocol, which is a
good way to fix this. More precisely: AJP13 ensures, that the web
container provides the Apache port, protocol and server name to the
webapp, if it asks about this data to produce a self referring URL.

If you use http between Apache and Tomcat instead, you need to set
additional attributes on the Tomcat connector to "fix" the data.

So I would say your webapp is broken, in that it asumes standard data
instead of using the servlet API to ask the container for the needed
data. Maybe there's a config item for your webapp.

Nevertheless you can play tricks, because the redirects are done using a
response header called "Location", which you can rewrite using mod_headers.

Have a look at

http://tomcat.apache.org/connectors-doc/generic_howto/proxy.html

and search for "Location", but do also read the rest of the page.

Rainer

Then either something is wrong with your JkMount (Apache not using it as
you intended), or the URLs of the images are broken in the sense, that
they are not beginning with /context/.

To sum up the previous discussion:

- if the image requests are not forwarded to Tomcat, then you need
JkStripSession to remove the session id

- if the images get forwarded to Tomcat and do exist, but they are not
served, then there should be some authorization problem with your webapp.

I don't understand, what problem you try to fix. The most common use case is

JkMount /myapp/*

which *will* forward requests for forbidden contant, like
/myapp/META-INF/... or /myapp/WEB-INF/... to the web container. This is
OK, because the SPEC says the container is *not* allowed to deliver such
content. You should get an error from the container, right?

As soon as you start to disable forwarding of this stuff, you are more
likely to run into trouble. Because now, if you also put the webapp
somewhere on the disk where the web server can deliver it, you have to
ensure, that the web server does not deliver this content. That's
because the web server is not aware of the special meaning of these URLs.

So why not letting mod_jk forward it?

Finally: Around 1.2.15 there indeed where changes to the interaction of
mod_jk and directory (index) handling. I don't remember the details
right now, but let's first focus on what kind of problem we want to fix
(if there is one).

This log snippet is not useful, because the request you used was for
/server-status, which is most likely not a request you want mod_jk to
send to JBoss.

Please post all your JK directives from your httpd.conf and the files
included in that. Also post your workers.properties, and if you use it
the uriworkermap.properties file.

The most common cause why simple setups do not work is the use of
virtual hosts in the Apache configuration. If you have virtual hosts,
you have to put JkMount into the virtual hosts, or you set "JkMountCopy
All" in the global part of the configuration.

If the file is loaded via a ClassLoader - then the JVM will cache it and

Yes, mod_jk supports 2.2 since a long time. The build uses the
apache-2.0 directory, because the mod_jk code for 2.0 and for 2.2 is the
same. That's normal.

Please post the steps you did in order to do the build.

If possible also post somewhere the results of configure.

Re: redirect paramter in the jk_workers file

Your mailer uses a very unfriendly way of formatting your messages. So I
do top posting.

Yes, as you can read on

http://tomcat.apache.org/connectors-doc/reference/workers.html

the atribute redirect is supported since version 1.2.9. For a two node
load balancer, you don't need it though. If you have many nodes in a
load balancer, the redirect expresses, which one you prefer for the
failover. If you dont specify it, the load balancer will use some other
working node according to its load values.

Rainer

Apache Server failover and session replication

Hello All,
I have a setup with two tomcat instances(A&B). I have configured
an apache web server 2.2 for load balancing and fail over. Setup looks fine
as per the configurations suggested. Let tomcat A be handling some request
at sometime. When tomcat instance(A) goes down, the session is replicated to
another tomcat instance(B) successfully. Now tomcat instance B is handling
those requests. Till this point everything goes fine, but when I bring up
tomcat instance(A) and after that tomcat instance(B) goes down, the session
is no longer replicated. What might be the issue? In status page of apache
server I see even if node status is OK session is not replicated to fail
over node for second time.


Thanks in advance,
Sumedh

There are too many unknown constraints to answer - but I'll try.

In app B - use an init parameter which is a filename where test.xml is 
located.


myfile
/usr/local/more/cowbell/test.xml


Then when app b needs to write the file;
File f = new File(servletContext.getInitParameter("myfile"));
FileWriter fw = new FileWriter(f);
fw.write(stuff);
...

If you need to read the file from app B, use a file reader. This is an

Actually, it doesn't switch which is the primary.  It keeps trying
the primary every time and failing over to the secondary every
time the primary fails.  When the primary comes back, it will
get the primary.

Basic logic is this:

try{
   conn = primary.getConnection();
}catch ( SQLException e ){
   conn = secondary.getConnection();
}
return conn;

I'm a little concerned that the first failure might take time
due to having to wait on a timeout or something like that.
That could kill performance, so that's one of the reasons
I'm asking about it here.

Eduard Pal wrote:

It's because of a combination of Windows quirks (or some might say flaws).
Whenever one unsets an environment variable (e.g. "set FOO="), the set
command sets the errorlevel (i.e. exit code) to 1. In Windows, commands do
not always set the errorlevel after exiting. When they do not, the
errorlevel keeps its previous value, which is whatever value it was set to
by the last command that did actually set it. For example "echo hello" or
"set FOO=queue" will not set the errorlevel at all. In catalina.bat, the
following line causes the errorlevel to get set to 1:

set JPDA=

None of the commands following that line set the errorlevel (at least not in
the case when the batch file was passed "start" as its first arg), so when
the batch file exits, the errorlevel is still set to 1. If catalina.bat was
called via startup.bat, startup.bat exits after catalina.bat exits and the
errorlevel is still set to 1.

A fix for this would be for catalina.bat to execute a command that is known
to set the errorlevel back to 0 after the "set JPDA=" line. For example:

set JPDA=
rem The above command sets the errorlevel to 1. The ver command will reset
the errorlevel to 0.
ver >nul

Here are a few arguments for upgrading the JVM and Tomcat
- the JVM is no longer supported by Sun
- the major Tomcat version (4.1.x) is no longer supported by the ASF
- the minor Tomcat version (4.1.31) has 9 important, 2 moderate and 16
known, published security vulnerabilities.

If an application is so critical it has to be that tightly controlled, I
have to wonder why that many security vulnerabilities are not a concern.
 Can it really be the case that none of them apply in your environment?

Re: Using multiple DataSource's for fail-over.

2009-09-02 Thread Bap


Bill,

If you are using Oracle RAC, then why dont you use a RAC JDBC URL that  
contains both nodes?
A DBCP testOnBorrow will ensure only current transactions on a node  
will fail if one of the nodes goes down, and all new requests for  
connections from the pool will "recover".


Bap.


Quoting Ognjen Blagojevic :


This is interesting topic.

IANA-failover-expert, but one question comes to my mind. What  
happens when the first server is recovered? Some cached connections  
will still point to second server, while newly created connections  
will go to the first one?


Is that acceptable?

Bill Davidson wrote:

Tomcat 6.0.20 using DBCP DataSource
Java 1.6.0_16

I've got two Oracle RAC nodes, mirroring each other.  My current fail-over
method if the primary node fails is to shut down the web servers,  
reconfigure

them to use the secondary node and restart the web servers.  Not pleasant.

I'm thinking I can make a "FailOverDataSource" that implements DataSource
and wraps around DataSource's for each of the two nodes.  Its  
getConnection()
method would try to use the getConnection() from the primary node,  
and if that

fails, it would try the secondary node.  Repeat logic for other DataSource
methods.  Instant automagic fail-over.  I've actually written it,  
and it seems
to get a hold of both DataSource's fine.  I can't kill the primary  
on an active

busy system to do a "real" test though.

I'm thinking I can't be the first person to think of this.  Are  
there any obvious

problems with this idea?

I thought the Oracle JDBC driver allowed for all the nodes to be placed 
into the connect string and the driver was smart enough to detect 
failover. [So its a configuration exercise on the connection string.]

Try a software firewall like iptables (linux) or the windows firewall. This way
you can simulate an in communication break, just like swithcing off the server.

Re: EL expressions not evaluation in tag library

So, you are saying the EL expressions are evaluated, but the standard

get rid of javaee.jar. I believe it duplicates servlet-api classes.

Ron,

Thanks for your reply.

The 'one hour off' problem was an install issue by the guy who brought up 
that server... wait a minute, that was me.


The mystery is that Tomcat will compile some JSP's just fine but will always 
stop on the same ones.  On the theory it was memory, I changed the Java 
memory options to match the current production server... no joy there.  To 
test the theory the problrm was the last date modified, I made certain the 
dates on all JSP's were one day before the server date (note that the dates 
on the JSP's that compiled were within seconds of those that didn't)... no 
joy here either.  If I copy .java files from development to server, the 
server will actually remove the .java files from the work directory so no 
joy there.  If I copy the .java and .class files from the development build 
directory to the work directory on the server, that appeared to work at one 
point but now the server removes those files from the work directory.  The 
JSP's that the server fails on are no larger nor no more complex than those 
it compiles.


I am bringing Netbeans up on the server so I can step through what's 
happening but have not yet got that running.

Carl

One way to find out what is going on is to use remote debugging and your
